So I've been working on/researching this song a whole lot and there are a few problems I've noticed in your tab but I'm sure my version isn't perfect either. Other-wise your tab is spot on! So here's what's wrong as far as I can tell:

The verse main riff orders are slightly wrong but I can't figure them out enough to correct them. What I've been playing verse 1 goes:

1, 1, 1, 2, 2, 2, 2, 2, 1, 2, 1, 2, 3, 4, 2, 2*, 1, 2, 2, 2, 3, 4--

Let me explain what riff 3 and 4 are:

Main riff part 3G|----------------------|D|----------------------|A|----------------------|E|--3--3--10-7-5-/-7-3--|

Main riff part 3G|----------------------|D|----------------------|A|----------------------|E|--8--8--10-7-5-/-7-3--|

Now the riff 2 with a star beside it means there's a weird jump, it's basically the same though, only it looks like this:

Main riff part 2G|----------------------|D|----------------------|A|----------------------|E|--0--12--10-7-5-----3-|

When we get to the chorus, there's a little difference towards the end:

Last lines of chorus:G|---------------------------------------------|D|---------------------------------------------|A|---------------------------------------------|E|-8-8-8-8-10-10-10-10-12-12-12-12-10-10-10-10-|Post ChorusG|--------------------------------------|D|--------------------------------------|A|--------------------7-6-4-2-----------|E|8-8-8-8-10-10-10-10---------12-10-8-7-|

Verse 2 order goes like this:

2, 2, 2, 2*, 2, 2, 2, 2, 3, 4--

I made an alternate tuning for this (Where you tune your A down to G# making the notes easier to reach, because after listening to the song enough I'm not really hearing these slides). Because it's so much different I'm going to go ahead and post it as an alternative to this tab! I'll give you credit at the bottom though, because you've helped me so much! :)
